Description and Introduction

Precision Micropower Series Voltage Reference The LM4128CQ1MF3.0 is a precision voltage reference manufactured by Texas Instruments (not National Semiconductor, as previously mentioned). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V  
- **Initial Accuracy:** ±0.2%  
- **Temperature Coefficient (Max):** 50 ppm/°C  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Current:** 10 mA  
- **Supply Voltage Range:** 4.5V to 12V  
- **Low Dropout Voltage:** 300 mV (typical)  
- **Long-Term Stability:** 50 ppm/1000 hours  
- **Package:** SOT-23 (5-pin)  

### **Descriptions:**
- The LM4128 is a high-precision, low-dropout voltage reference with excellent temperature stability and low noise.  
- It is designed for applications requiring stable voltage references, such as data converters, power supplies, and instrumentation.  
- The device features low quiescent current and is available in multiple output voltage options.  

### **Features:**
- **High Accuracy:** ±0.2% initial voltage tolerance.  
- **Low Noise:** 35 µVpp/V (typical) from 10 Hz to 10 kHz.  
- **Low Dropout Operation:** Suitable for battery-powered applications.  
- **Low Quiescent Current:** 300 µA (typical).  
- **AEC-Q100 Qualified:** Suitable for automotive applications.  
- **Reverse Battery Protection:** Protects against incorrect power supply connections.  
- **Wide Operating Range:** Supports industrial and automotive environments.  

This device is ideal for precision analog circuits where stable voltage references are critical.
